NVT AI Chatbot connects your WordPress site to the NVT SaaS platform to deliver an AI-first support experience for WordPress and WooCommerce stores.
The plugin focuses on three core jobs:
<ul>
<li>Answer with your own knowledge base: Use Retrieval-Augmented Generation (RAG) so the chatbot answers from your website content and uploaded documents.</li>
<li>Escalate to a human when needed: When AI is not enough, visitors can switch to Live Chat and your team can continue the conversation from the built-in Inbox.</li>

</ul>
Main features:
<ul>
<li>AI Chatbot (RAG): Grounded answers based on your website content and uploaded files.</li>
<li>Website Crawl + File Ingestion: Crawl your site manually or on a schedule, or upload files such as PDF, DOCX, TXT, MD, HTML, CSV, XLS, XLSX, and PPTX.</li>
<li>Live Agent Handoff: Switch between AI and Live Chat using schedule rules, manual override, or user request.</li>
<li>WooCommerce Product Support: Search products, recommend items, and show product cards inside chat.</li>
<li>WooCommerce Cart Actions: Add to cart from chat, refresh cart summary, update quantities, or remove items.</li>
<li>WooCommerce Checkout Assist: Detect checkout requirements, collect required fields, show payment methods, and create an order from chat when your store supports it.</li>
<li>Order Lookup: Surface recent order information for logged-in or identified customers.</li>
<li>WooCommerce-Aware Agent Inbox: Support agents can see useful context such as contact info, last seen page, recently viewed pages, cart snapshot, and recent orders.</li>
<li>Personalized User Context: Logged-in WordPress/WooCommerce users can be recognized automatically for more relevant support.</li>
<li>Live Chat Uploads: Visitors can send images, documents, and voice messages during live chat with staff.</li>
<li>Widget Customization: Choose theme mode, colors, avatars, widget position, welcome message, sound, and custom button image.</li>

<li>CSV Export: Export leads and full conversation history from the Inbox.</li>
<li>Admin Notifications: Unread chat badge and real-time admin notifications help your team respond faster.</li>
</ul>
This makes the plugin suitable for:

Inqyra adds an intelligent chatbot to your WordPress site that answers visitor questions based on your pages, posts, and documents. Connect your own AI provider, keep your data on your server, and pay only what the AI actually costs.
Bring Your Own Key (BYOK) — You connect directly to your AI provider. No middleman, no markup. A typical conversation costs ~$0.003 with GPT-4o-mini.

<ol>
<li>Crawl — Inqyra indexes your pages, posts, and custom post types</li>
<li>Embed — Content is converted to vector embeddings entirely in your browser (your content never leaves your server)</li>
<li>Search — When a visitor asks a question, Inqyra finds the most relevant content using vector similarity, keyword matching, and title/path boosting</li>
<li>Answer — The relevant context is sent to your chosen AI provider, which generates a grounded response</li>

<h3>External services</h3>
This plugin connects to external third-party services to provide AI chatbot functionality. All connections require the site administrator to explicitly configure an API key before any data is sent. No data is transmitted without the administrator’s action.
<h4>AI Chat Providers</h4>
When a visitor sends a message through the chat widget, the visitor’s message along with relevant content from your website (retrieved via RAG search) and the system prompt configured by the administrator are sent to the chosen AI provider. The administrator selects which provider to use and provides their own API key. Only one provider is active at a time.

<h4>HuggingFace Transformers.js (ML Inference Service)</h4>
This plugin uses the Transformers.js library to perform machine learning inference entirely in the browser for generating vector embeddings. The JavaScript library itself (~850 KB) is bundled locally within the plugin at <code>assets/js/vendor/transformers.min.js</code>.
When the administrator triggers content indexing, the library downloads the ML model files (~50 MB) and WebAssembly runtime from HuggingFace CDN to the user’s browser. This is a service — the model files cannot be bundled locally in the plugin due to their size.
No website content or user data is sent to HuggingFace — the model runs locally in the browser after download. The CDN only serves the model files.
Library: @huggingface/transformers v3.4.1 (bundled locally) 
Model: Xenova/paraphrase-multilingual-MiniLM-L12-v2 (loaded from huggingface.co at runtime)

<h4>Freemius</h4>
This plugin uses Freemius for license management, plugin updates, and optional usage analytics. When the plugin is activated, Freemius may communicate with its servers to validate licenses, deliver updates, and collect anonymous usage data (if the user opts in). Users are prompted for consent before any analytics data is collected.
